Abyssal Depths

Abyssal Depths is a port of the mod Aquatic Abyss

This mod adds sea life to the (pre-1.13) barren oceans of Minecraft, some based on real animals and others on mythical ones, and adds seaweed and rock formations. These features will liven the oceans for a much more interesting underwater experience.
